(CNN)A newly uncovered video of a resident at an assisted living facility in Florida mercilessly beating another resident raises new questions about the safety of the elderly in places meant to protect and care for them.

In the video, obtained last week, a 52-year-old resident is seen punching an 86-year-old resident with dementia more than 50 times as the older man lay curled up on the floor.

The younger resident accused the older resident of eating his cupcake, according to law enforcement.
